Before it dies, though, it emits these messages: OK. Have pulled in all the latest stuff from RELENG_2_2, and it no longer crashes the machine, but neither does it work... :-( Using "cdplayer" from the xcd port, and issuing the commands CD> play 1 2 (actually any play or msfplay command can be substituted) CD> stop CD> msfplay 0 2 0 1 2 0 This is what the console shows: cd0(ahc0:2:0): SCB 0x0 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x5 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa cd0(ahc0:2:0): Queueing an Abort SCB cd0(ahc0:2:0): Abort Message Sent cd0(ahc0:2:0): SCB 0 - Abort Completed. cd0(ahc0:2:0): no longer in timeout ahc0:A:2: no active SCB for reconnecting target - issuing ABORT SAVED_TCL == 0x20 Timedout SCB handled by another timeout sd0(ahc0:0:0): SCB 0x2 - timed out in message out phase, SCSISIGI == 0x0 SEQADDR = 0xa1 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa sd0(ahc0:0:0): SCB 2: Yucky Immediate reset.

Oddly, it only seems to be the msfplay command that causes the error, and only if used *after* stopping another play command. After the sequence above has occured, and the device closed and reopened, an msfplay command succeeds; issue "stop" then another msfplay and the same error repeats. -- Andrew.
